Review on 🏃 Nathan Men’s VaporKrar 4L 2.0 Hydration Pack/Running Vest - 4L Capacity with Twin 20 oz Soft flasks, Hydration Backpack Ideal for Running, Marathon, Hiking, Cycling by James Eledge

The fit of this vest is amazing, very soft shirt-like material (but much stronger). The vest has a simple, functional design with the ability to place a bottle in the front/bib and bladder sleeve in the back. Side (underarm) stretch pockets are good in theory, but hard to reach, so not very useful. I also didn't like the Velcro straps on the front pockets that snag soft materials. I liked the fit but the vest ended up being too short for my needs.
